Police were called to 49 Kensington Lane around 10 a.m. Monday after family members of Dr. Eduardo and Sonia Quesada could not reach them.

When police arrived at the home, they found Sonia dead and Eduardo unconscious. He was taken to the hospital and his condition is unknown at this time.

Police said there were no visible signs of trauma to either of the victims, but there was what's considered to be a large amount of prescription medication found nearby.

The home where the Quesadas were found belongs to Eduardo's mother. She is OK and has talked with investigators.

The Quesadas were injured in a home invasion on Proclamation Court in Bedford in November.

On Kensington Lane Monday, neighbors said that just before noon, several police and rescue vehicles were parked in front of Norma Quesada's home.

"Our first thought was maybe she had an alarm system in the house and it went off, and she wasn't here or they responded to it, because they left, and there was no crime scene. There wasn't anything," said Juliana Taylor, president of the homeowners' association. "We came back now two hours later, and it's, like, no, something is going on."

Police are not saying that this time if they believe Mrs. Quesada's death is a homicide or a suicide.

The county attorney and Attorney General's Office are involved in the investigation.
